COOKING-STOVE.

Specification of Letters Patent No. 4,284, dated November 26, 1845;Antedated August 30, 1845.

To all whom it may concern Be it known that I, ELI O. ROBINSON, of thecity of Troy, in the county of Rensselaer and State of New York, haveinvented new and useful Improvements in Stoves; and I do hereby declarethat the following is a full and exact description, reference being hadto the annexed drawings, making part of this specification.

In the drawings referred to Figure l is a perspective front view of thestove to which these improvements have been applied. Fig. 2 is a sideview of the same, With the top and one of the side plates Qfl", showingthe fire chamber at A; the oven at B, extending the entire length andbreadth of the stove with the exception of a flue at each end, as at aand 5. These flues, in connection with the horizontal passage 0 underthe oven, from a continuous flue passage for the fire and heated airfrom the fire chamher, after passing over the intermediate section ofthe oven to be carried entirely around it and up in front of the fireplace to the top of the flue b, from which a passage is provided on eachside, as at (Z, d, and as a continuation of the same flue along the topof the stove to the cross passage at the back end with which theycommunicate, as there shown at e e, and thence directly to the stovepipe which is placed over the cir cular projection at f. This crosspassage as shown by the drawings is made to project to the extent of itswidth back beyond the upright part of the back plate of the stove, whichof course leaves the entrance or draft from the fire into the descendingflue a on the inside of the inner side plates of this passage, so thatby means of the openings as shown in those plates and common slidingdampers by which they are closed and reg ulated the draft from the fireplace is directly through the openings to the stove pipe, or by closingthem turned into the descending flue and around the ovenin the mannerabove pointed out. The side passages extending' along the top of thestove are represented in the drawings as pro ecting over the uprightpart of its side plates to the extent also of their width,notwithstanding which I construct them at my 0ption so as to projectmore or less on one side or the other or both of the upright parts ofthe side plates of the stove, the object of the improvement in thisparticular being to provide for a continuation of the flue or draft fromthe top of the vertical flue b, in front to the cross passage in rearand thence to the stove pipe without any prejudicial interference withthe boiler openings in the top plate.

It may here be explained that the middle passage 9 is intended torepresent, as an alternative improvement, a central passage across thestove to be used or not with or without the others at discretion. Ifused without and as a substitute for the side flues the cross back fluewith which they communicate is also dispensed with and the middlepassage made to terminate directly under the stove pipe and in immediatecommunication with it. In which case a direct passage for the draft fromthe fire to the stove pipe will be through the openings shown in theside plates of this middle passage at h, it. By closing these by meansof dampers with which they are to be supplied the draft is turned downaround the oven as in the other case. If, however, the middle passage isomitted altogether the openings in and out of the same as represented inthe plates with which it is connected at each end are omit-ted also; andint-hat case the openings and dampers of the inner plate (as it willthen be in one) of the back flue are to be adapted to each other for thepurposes of the improvement accordingly.

In Fig. 3 at 2' is shown a plate extending horizontally across theovenmade to rest at each end upon cleats so as to be easily taken out orreplaced. This with the small openings -in the door of the oven as shownat y in the same figure and which when the door is closed come againstthe space between the plate and the top of the oven constitutes what Icall (from the free admission of air through these openings, the likebeing provided on each side) a cold air chamber for the purpose ofregulating the temperature of the oven or guarding against the eflectsof too much heat from its top plate.

At K, Fig. 1, is an article connected as an appendage to the front plateof the stove, with boiler openings and the usual provisions inside forfire, &c. At Z is an opening closed with a lid for the introduction offuel. on, m, are openings in front with dampers for supplying andregulating the draft to the fire. At n, n, as seen through the boileropenings are openings for a draft from the fire place of this appendageinto the ascending flue in front of the stove.

When the appendage is taken off these openings are closed by dampers.The sunk hearth in the projecting bottom plate of the stove underneathshown at 0, Fig. 2, is provided as receptacle for ashes and otherdroppings from the fireplace of this appendage. Fig. 4 is a back view ofthe same article representing the openings through its back plate fittedto those provided for them in the front plate of the stove, the formerbeing made to project so as to set therein as in a socket in support ofthe entire article while the small vertical projections from the upperedge of its back plate at p, p, F ig. 4, by being introduced into theinverted sockets provided for them at each edge of the front plate ofthe stove as shown at 1' 1-, Fig. 1, serve to keep the Whole in placewhen attached to the plate for use and to allow it to be taken off andremoved when not wanted. It may also be attached and secured in itsplace when required by any other common mode of fastening.

WVhat I claim and desire to secure by Letters Patent are j i The fluepassages across the top of the stove for the fire and heated air, afterthe same have been made to pass around the oven and up to the top of theflue b in front of the fireplace to be continued to the stove pipe asabove described.
